Can I take Amitriptyline and Gabapentin together?

Guide för läkemedelsinteraktioner

Taking amitriptyline and gabapentin together can make you feel very sleepy, dizzy, or confused. It can also make it harder to concentrate and may slow down your breathing or affect your coordination, increasing the risk of falls.

Varför detta händer

Both medicines work by slowing down activity in the central nervous system (the brain and nerves). When used together, their sedative effects add up, making the overall impact on your body much stronger than if you took either medicine alone.

Use this combination with caution. Do not drive, operate heavy machinery, or perform dangerous tasks until you know how these medicines affect you. Avoid drinking alcohol, as it will make the sleepiness much worse. If you feel extremely drowsy, have trouble breathing, or feel very unsteady on your feet, contact your doctor immediately.

Suicidal thoughts and mood changes

Both medicines can increase the risk of suicidal thoughts or self-harm, particularly when first starting treatment or changing doses. Seek immediate medical help if your mood changes or you feel depressed.

Severe breathing problems (Respiratory Depression)

Gabapentin can cause serious, life-threatening breathing difficulties, especially if you already have lung disease, are elderly, or take other sedating medicines like opioids. Seek emergency care if you experience shallow breathing or extreme sleepiness.

Heart rhythm disorders (QT prolongation)

Amitriptyline can affect your heart rhythm. It must be used with extreme caution if you have a history of heart disease, a recent heart attack, or are taking other medicines that affect the heart's electrical signals.

Alkohol

You should avoid or strictly limit alcohol while taking these medicines. Both amitriptyline and gabapentin cause drowsiness and dizziness; alcohol significantly increases these effects, which can lead to dangerous levels of sedation, impaired coordination, and breathing difficulties.

Caffeine (Coffee, Tea, Energy Drinks)

Amitriptyline can sometimes cause a fast or irregular heartbeat. High amounts of caffeine can worsen these side effects and may also interfere with the sedative effect of the medicine if you are taking it to help with sleep.
